PEEK Tube Introduction and Characteristics
Polyether ether ketone resin (PEEK resin) is a new type of semi-crystalline aromatic thermoplastic engineering plastic prepared by condensation of 4,4’-difluorobenzopheneone and hydroquinone in the presence of alkali metal carbonate with diphenylsulfone as solvent. It’s high temperature thermoplastic plastic with high glass transition temperature（ 143℃ ）and melting point（ 334℃ ）. Its load thermal deformation temperature is as high as 316℃(30% glass fiber reinforced or carbon fiber reinforced PEEK). It can be used in 250℃ for a long time. Compared with other high temperature resistant plastics like PI, PPS, PTFE and PPO, the upper limit of operation temperature of PEEK is nearly 50℃ higher.
1:High temperature resistance.The long-term using temperature certificated by UL is 260℃. Even if the temperature is as high as 300℃, it can also maintain good mechanical properties.
2: Wearing resistance. Under many harsh environment like high temperature, heavy load and strong corrosion, PEEK and its compound materials are in good property of wearing resistance.
3: Self-lubricating. PEEK possesses lower friction coefficient and can realize operating without lubricant. It can serve long time work in mediums like oil, water, steam,weak acid and base.
4: Corrosion resistance. PEEK tube is insoluble in ordinary solvents.It enjoys good corrosion resistant property for all kinds of organic and inorganic chemical reagents.
5: High strength. PEEK tube has high mechanical strength, rigidity and surface hardness.
6: Easy to process. Parts can be manufactured by injection molding.They can also be post processed by turning,milling, drilling, tapping,splicing and ultrasonic welding.
7: Hydrolysis resistance. PEEK tube products can continuously work for thousands of hours without obvious degradation of performance in steam over 250℃ or water under high pressure.
8: Flame retardant. Without the use of any additives,the flammable level of PEEK sample with 1.45mm thickness is UL94 V-0.
9: Low smoke and innocuousness. The smoke and gas are low while burning
10: Electrical performance. PEEK can maintain stable and outstanding electrical performance in a wide range of temperature and frequency.
11: Radiation resistance. PEEK has excellent Radiation resistance property of high dose γ rays. The mechanical properties can be saved completely to serve as Radiation resistant parts in nuclear equipment.
12: Stable size./Dimensional stability.
